rxs100 exhaust

Discussion in '2 smokers' started by Deleted281759, Aug 9, 2013.

  1. hey, not sure if this is the right forum to be on.. but as i already use it i guessed it would be okay...

    i have just picked up a yamaha rxs100 for £200! it needs some body work touching up and one of the carbs need cleaning. just a general clean up.

    but the exhaust is bent and has a crack from the previous owner backing his car up into it -.-

    does anybody know where i can get a good sounding aftermarket exhaust for this bike?

    also with exhausts, does any exhaust fit anybike? or do you have to find special ones made for the bike?

    for example i only see the reverse cones on triumph scramblers.

    thanks for your help

    That's a 2-stroke. You're going to need either a stock pipe or someone may make an expansion-chamber for it. 2-strokes are finicky about exhausts. If nothing else , it could probably be welded.
  3. how hard is it to make an expansion chamber?

    You would need pretty accurate dimensions for any improvement. You might be able to make one for something else fit. Another 100cc single or 1 pipe off of a 200 twin.
  5. that why i dont want to try myself... it would be too accurate for me. do you know of any bikes that have an exhaust i could use?

    harder than you think.....

    best is repair or replace.....with the proper one - can't mix and match 2 stroke exhausts much, although joexr is right, a 100cc pipe from something else might be close enough - but a pipe designed specifically for that engine will be much better...... the reverse cone silencer you mention is a 4 stroke muffler - you need to stick with 2 stroke stuff if you want it to run right...

    p.s. it's never gonna sound like a triumph scrambler :D
  7. oh no, i know that its just for scrambler... i meant i dont see the reverse cones on any other bike :) my dad has this, his bike only has been basically everywhere and still runs like a dream :) wish i was liucky enough to have that bike
